Title:
ACRYLIC RESIN PARTICLE
Document Type and Number:
Japanese Patent JP3662875
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To obtain acrylic resin particles excellent in handling and flexibility at normal temperature.
SOLUTION: The acrylic resin particles having a multilayer structure consisting of an inner layer mainly comprising an acrylic acid ester copolymer having ≤0°C glass transition temperature and an outer layer mainly comprising a methacrylic acid ester copolymer having ≥60°C glass transition temperature are produced by polymerizing the methacrylic acid ester-containing monomer to obtain the resin having ≥60°C glass transition temperature to be the outer layer, subsequently dissolving the resin in the acrylic acid ester-containing monomer to be the inner layer to obtain a solution which is polymerized in suspension.
